Guitar girl or hot dog girl? You decide!
I can only assume this is supposed to be armor that has been broken and torn? I can't think of another explanation for the strips of fabric over the chest and groin.
She looks like she's wearing a guitar, or like she's cosplaying as a hot dog and that's a ketchup and mustard strip down her body?
